Android 使用GPS和网络获取用户位置LAT LNG

您是否在设置中同时启用网络定位和GPS定位?据我所知,对于Android ICS(4.x)和更新版本,由于安全问题,您无法以编程方式启用/禁用位置访问。试着在安卓2.x上测试一下。希望这有帮助。您可以使用新的融合提供程序快速获取用户位置,而不会混淆 新的Google Play服务简化了位置问题,例如根据您的优先级自动选择最佳提供商 这里是一个示例请求
private static final LocationRequest REQUEST = LocationRequest.create()
.setInterval(20000) // 20 seconds
.setFastestInterval(16) // 16ms = 60fps
.setNumUpdates(4)
.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
确保您在SDK管理器中更新了Google Play服务,并查看此链接以获取有关如何使用新Play服务获取用户位置的信息。
您是否同时请求精细和粗略位置数据的许可?你需要同时做这两件事。我不明白你的意思。请在你的清单中解释,你需要请求获得位置数据的权限。有两种权限-精细和粗糙。如果你想要网络和gps数据,你需要两者。是的,我已经添加了这两个。你在哪里调用showLoc()方法?否则,将不会有requestLocationUpdates,您只能获得一个且唯一的位置。它是通过单击按钮调用的
